KENNETH HOWIE, OF NORRISTOWN, PENNSYLVANIA MENTS, TO WILDMAN MFG. 00.,OF N TION' OF PENNSYLVANIA ASSIGNOR, BY MESNE ASSIGN- ORRISTOWN,PENNSYLVANIA, A CORPORA- PATTERN WHEEL FOR KNITTING MACHINES.

Application filed February To all whom it may concern:

Be it known that I, KENNETH HOWIE, a citizen of the United States, andresident of N orristown, Pa., have invented certain new and usefulImprovements in Pattern Wheels for Knitting Machines, of which thefollowing is a specification.

y invention concerns pattern means for acting upon knitting instrumentsto control their actions to knit or tuck according to the patterndesired.

In the accompanying drawings. Fig. 1 is an edge view of a trick wheel inconnection with latch needles.

Fig. 2 is a. view like Fig. 1 but looking from the opposite direction.

Fig. 3 is a plan view of the composite trick wheel.

The composite trick wheel consists of a lower disc or wheel 9 having anupstanding rim or flange 10, and a smaller diameter inner wheel or disc11 arranged eccentrically to the lower member and having its uppersurface in the same plane with the upper face of the upper edge of theflange or rim. In these faces shallow grooves or notches 12 are outwhich are adapted toreceive-the butts 13 of the latch needles. Theseshallow notches are closed at their bottoms to afpports for the needlebutts and as the wheel is set in inclinedposition the needles will belifted to knitting ofl? position. The two discs are also provided Withdeep or clear-through notches or teeth 14' and when two of these notchesalign the butt of the needle will pass therethrough. in tuckingposition. as shown at B Fig. 1, and this needle will tuck.

The two wheels or discshave their peripheries coinciding at one point,or substantially so. because of their eccentric relation as at C.

A cam 15 is associated with. the trick wheel which guards the needle intucking position.

I claim: 1. In a knitting machine, knitting instruments, and a trickwheel composed of two discs, one having a flange with its edge 2, 1921.Serial No. 441,879.

lying in the plane of the face of the other wheel, said wheels being ofdifferent diameters, placed face to face and on displaced axes, saidwheels having each shallow notches for knitting and other notches fortucking which notches act as drivers by contact of their walls with thebutts of the knitting instruments, said notches in each wheel beingspaced according to the needle spacing to be driven thereby,substantially as described. 2. In combination in a knitting machine,knitting instruments, and a trick wheel arranged at an inclination.composed of two discs of different diameters arranged relatively ofi'center and in substantially fixed relation to each other and havingnotches to engage the knitting instruments to be driven thereby, some ofsaid notches in each disc having closed bottoms to engage and lift theknitting instruments for knitting, and others of said notches being cutclear through the discs from the upper to the lower face to allow thebutts of the instruments to pass therethrough in tucking position. eachof said wheels being turned by their notches engaging the needle buttssubstantially as described.

3.- In combination in a knitting machine, knitting instruments, and atrick wheel arranged at an. inclination, composed of two discs ofdifferent diameters arranged relatively off center and in substantiallyfixed relation to each other and having notches to engage the knittinginstruments to be driven thereby, some of said notches in eachdischaving closed bottoms to engageand lift the knitting instruments forknitting, and others of said notches being cut clear through the discsfrom the upper to the lower face to allow the butts of the instrumentsto pass therethrough in tucking position, each of said wheels beingturned by their notches engaging the needle butts and cam means foracting on the needle butts in tucking position.

In testimony whereof, I afiix my signature.

KENNETH HOWIE.
